Joint table-toppers Kilkenny, who face Dublin tonight, have been forced to make changes to the side that beat Waterford last week.

Paddy Hogan and Conor Fogarty come in to replace the injured Tommy Walsh and JJ Delaney in the half-back line and Paul Murphy replaces Pat Hartley in midfield.

Michael Fennelly has recovered from the back problem that led to TJ Reid replacing him before throw-in last week and Matt Ruth replaces John Mulhall at half-forward.

Meanwhile, Cork footballer Colm O'Neill has succumbed to a second cruciate injury in four years. A second scan on the injury he picked up against Galway has confirmed the prognosis for the talented 22-year-old forward.

Galway hurling boss John McIntyre has made two changes to the side that beat Dublin for tomorrow's clash with All-Ireland champions Tipperary.

David Collins is forced out with a shin injury and is replaced by Ger O'Halloran. Iarla Tannian returns up front in place of Joe Gantley.

Galway and Tipp have both racked up 14 yellow cards this season, double that of Division 2 table-toppers Limerick, who have the cleanest disciplinary record on hurling's 'Fair Play' index. The Shannonsiders are marginally clear of Cork (eight yellow) and Antrim (seven yellow, one red). Fermanagh, with 16 yellow cards and four reds, have the worst record.

Kerry's footballers have the best disciplinary record in the NFL, with just eight yellows and two red cards to date. Monaghan (13 yellows) and Louth and Wexford (14 yellows each) are rated the next cleanest; Wicklow and Meath's footballers have the worst records.

Wicklow have amassed 34 yellow cards and two reds in their seven league games, but Meath are rated worse: they have picked up their 30 yellows and two reds in just five games.
